Section 1: Installing Sprocket on a Freewheel

Flip the bike over and let‘s install a motor.

Section 2: Installing Sprocket on Coaster Brake Hub

Note: A joint binder may be needed on both sides of the sprocket for chain alignment on some non-coaster brake bikes.

STEP 10.

Place the brake arm in a vise (heat will make bending easier and more precise). A hammer and brute force will work in this application as well.

STEP 11.

After the bend is complete, install the brake arm and spin the wheel to check for clearance. If the arm clears the bolts, attach the wheel to the bike and get ready to install your motor.

STEP 12.

Now that you have installed the rear wheel and checked to see that it spins true, it‘s time to move on to the motor.

Note: There are many ways to install your motor and people are coming up with new mounting ideas every day. We will be touching on a few different ones.

Section 3: Installing Motor

STEP 17.

Drill four ³“ holes for the U-bolts on the bottom part of the mount as shown.

Note: If using the factory holes, it‘s best to drill the frame holes with your bike upside down. Follow steps 19 and 20 to mark where to drill the holes.

STEP 21.

After adjusting the fit of the motor, mount the bolt into place using two U-bolts purchased at your local hardware store.

Note: Don‘t forget the strips of rubber if you wish to protect the finish of your bike frame. Also, if you had to make adjustments to the mounting bracket you may want to touch up any scratches with black paint.

Section 4: Installing the Clutch Lever and Clutch Cable

Section 5: Installing the Chain

STEP 29.

Note: The chain should be as tight as possible, but it may not be possible to get it perfect. The chain tension adjuster will pick up the slack in the following steps after the chain has been shortened.

Section 6: Installing the Carburetor and Throttle

Section 7: Installing Ignition Box and Gas Tank

STEP 50.

Cut the fuel line provided in the kit to the proper length. Then slide it onto both the ends of the petcock fuel valve and the inlet on the carburetor.

Note: It‘s a good idea to get an inline filter for your fuel line. The petcock does have a screen filter, but small sediment can still get through.

Section 8: Installing the Chain Guard and Exhaust

Congratulations! Your Livefastmotors motor kit is now installed.

GENERAL SAFETY PRECAUTIONS

  1. Obey all traffic regulations.

  2. Do not operate bike without the chain guard installed.

  3. Always wear a helmet and eye protection when riding.

  4. Do not wear loose fitting pants or skirt when riding, as loose fabric can catch in the drive chain and cause an accident.

  5. Remember that you are riding a small, motorized vehicle and other traffic may not be able to see you. Wear bright colors on your shirt and helmet.

  6. Never ride at night without proper headlight, taillight, and reflectors. Be sure to wear reflective clothing when riding at night.

  7. Never ride on pedestrian throughways or sidewalks, especially with the engine running.

  8. Never operate your MOTOcycle in an unsafe manner.

  9. Wear riding gloves to prevent injury to hands during an accident.

10.Check local and state laws before riding your MOTOcycle on the street. 11.WARNING“ ALWAYS WEAR A HELMET WHILE RIDING!!

OPERATING SUGGESTIONS

EXHAUST SYSTEM:

After 20 hours of operation, check the exhaust pipe for excessive oil and carbon buildup. Be sure to use the supplied support strap to secure the exhaust muffler to a solid anchor point on the bike frame or engine.

  1. Remove the exhaust pipe cp by loosening the retaining screw.

  2. Pull the cap and baffle out of the pipe.

  3. Clean with degreaser, rinse and dry.

  4. Re-assemble.

Note: Excessive periods of low-speed operation, idling, or leaving the fuel petcock in the —on“ position during shutdown periods may cause the pipe to become clogged with unburned fuel.

CHAIN:

Every time the bike is ridden, check the tension of the drive chain.

  1. Roll the bicycle forward to remove slack from the bottom of the chain.

  2. Find the center and push downward on the top of the chain while measuring the deflection.

  3. Tighten the chain if the deflection is more than ² inch. This is done by raising or lowering the adjustment on the chain tensioner roller.

FASTENERS:

Tighten all fasteners after every 5 hours of operation. 8 mm diameter cylinder head bolts and motor-mounting studs should be tightened to 9-10 ft./lb. using a torque wrench. Check before each and every ride. Use thread locker and lock washers on all connections.

RIGHT-SIDE GEARS:

Remove the cover plate and keep a small amount of heavy grease on the gear train. Do not over-grease, as leaks will occur and also may adversely affect the clutch operation. Regular greasing, if required, will help reduce gear wear and keep the gear train quiet. Check the gears weekly. Remove old debris and apply a small amount of grease to the inside of the gear teeth.

BRAKE PADS:

Fresh brake pads and clean rims assure proper braking.

STARTING AND OPERATION INSTRUCTIONS

  1. Mix 6 oz. of 2-stoke oil (16 : 1 ration) to 1 gallon of fuel in separate container. Shake well to mix and fill the gas tank (1/2 gallon capacity). Do not overfill. Remember to put the fuel cap back on.

  2. Open the fuel valve. Small lever pointed down with fuel line is in the open position.

  3. Depress the small, round cap plunger (tickle button) to prime the carburetor. It is located on the left side of the carburetor next to the idle adjust screw. One or two times should be enough.

  4. Lift the choke lever to the —up“ position. It is the small lever on the right side of the carburetor.

  5. Pull the handlebar clutch lever inward, to disengage the engine from the rear wheel.

  6. Start to pedal œ downhill if possible for the first start.

  7. Let out the clutch lever all the way and continue to pedal. The result is a direct engine hook up with the rear wheel via the chain and sprocket, and the engine will now turn over (start spinning). Pedal until the motor starts. Accelerate slowly at first.

  8. Twist the throttle to increase speed, reverse twist the throttle to decrease speed. To stop, disengage the clutch and apply the brakes. To accelerate, pedal and release clutch while opening the throttle.

  9. Adjust the choke to the smoothest engine running position.

  10. After warming up the engine, push the choke lever all the way down. If the engine races too fast or too slow, pull the clutch lever and lock in the notched catch. Stop and adjust the engine rpm.

  11. If the rpm needs adjusting, turn the idle adjust screw (left side of carburetor) in or out slowly, to obtain the proper idle speed of about 1400 rpm =/- 100 rpm. To correctly break in the engine, do not exceed 20 mph or 30 minutes of continuous running time for the first 50 miles.

  12. To stop the engine, push the Kill Switch and turn off the gas valve at the tank. Turning off the gas will prevent fuel from being siphoned from the tank. Warning note: Never leave the fuel-tank gas valve in the open position when the engine is not running or when the bike is in storage.

  13. After and before each ride, check all of the mounting fasteners, including the axle and brakes.

  14. After using the first gallon of gasoline, the next fuel mix can be at 32:1 gas to oil ratio. Use a high-grade, synthetic 2-cycle motorcycle oil. This can be purchased at most motorcycle shops or lawn and garden shops. After the engine is well broken in (after several hundred miles), a gas-to-oil ration of 50:1 can be achieved using a high-grade synthetic oil similar to that used in chain saws. Warning note: Engine lockup or piston seizure due to improper gas/oil mixture will not be covered by your engine‘s factory warranty. It is the responsibility of the owner/operator to make sure the gas and oil are mixed correctly.

Note: I used non-synthetic oil during my first gallon mix at break-in to promote break-in wear. Then in the later mixtures, I used synthetic oil only for clean burn, low wear, and long engine life.

Pull Start Installation

Clamp one side at a time in vise. Apply heat, make RED hot to bend. Cool with water after each bend. Bend as evenly as possible. Bend both sides for balance.

Installation Instructions

Congratulations on choosing your new Livefastmotors motorbike kit accessory package. We offer these instructions to guide you through the installation. Please read through the instructions before beginning your installation. Happy motoring!

Accessory Kit Installation

Step 1.

Mounting the Headlight

The headlight bracket included in your kit is mountable on the front fork. You can mount it above or below the wheel line. Be sure to give yourself room for the spokes.

Shown here installed below the wheel line.

Step 2.

If you prefer an alternative to the front fork placement, you can easily make your own bracket out of a steel or aluminum bar purchased from your local hardware store.

Step 6.

Decide where on your bike you want the light installed.

You can easily install the headlight on the handlebars by bending your newly fashioned bracket around the bar, and drilling another hole that lines up with the hole drilled in step five.

Step 7.

If you prefer, you could bend the bracket into an —L“ shape and mount it to the front fork, above the wheel and behind the brake caliper.

The light installs easily and does not affect the braking of the bike.

Note: Most bicycle forks have a hole for a front brake caliper even if there is no brake caliper.

Step 12.

Programming the Computer

Press and hold the button on the front for 3 seconds; then let the button up.

Choose between —kph“ or —mph“ by pressing the button. The display will change each time the button is pressed. When your choice shows on the display, press and hold the button for three seconds and release. Now you must calibrate the wheel.

Wheel Calibration Table

Wheel Diameter in Inches: 16“ 18“ 20“ 22“ 24“ 26“ 28“ 28 x 1 ²“

Wheel Circumference: 128 144 160 176 192 208 224 228

Step 13.

Now your display screen will show three zeros.

Choose your wheel size from the calibration table above. The corresponding wheel circumference number directly below it is the number you will select.

Begin pressing the button -the numbers will Increase in increments of one.

After the tenth time the button is pressed, the numbers will begin to change rapidly.

Press the button to stop. Try to stop it just before the calibration number you are using. If you‘re setting it for a 26“ wheel, stop at 200 and move to 208 one number at a time. Once you have reached 208, press and hold the button for three seconds and the computer is set and calibrated.

If you pass your target number, simply start over.

Once setup is completed you can change between the functions by pressing the button once for each function.
